Titlul: 'Impunerea unui consens'
Semneaza: Sylvester Lajos
'Cititorii publicatiei 'Haromszek' -cu foarte putine exceptii- au receptat alegerile din Ungaria ca pe o înfrângere. (...)
Rezultatele finale ale alegerilor au adus totusi ceva nou si anume recunoasterea faptului ca între cele doua forte egale trebuie sa se creeze un echilibru. In caz contrar, tara nu poate fi guvernata. 'Infrânt', Orban Viktor este acceptat acum chiar si de Hankiss Elemer si de postul de televiziune 'Magyar ATV'. Se vorbeste despre impunerea unui consens. Este într-adevar nevoie de asa ceva. Speram ca legea statutului, proiectul-Szechenyi, creditele pentru locuinte, împrumuturile destinate elevilor si toate celelalte vor fi aprobate în varianta lor actuala. In acest caz, consensul impus, consensul national si maghiarimea europeana numarând 15 milioane de membri vor putea sa existe. (...)'

Paginã realizatã de IOAN STANCIU Bazele teoriei spaþiilor neeuclidiene au fost elaborate la Timiºoara „... Din nimic
am creat o altã lume, nouã“
Dintr-o fericitã întâmplare, datoratã în bunã parte hazardului, la începutul secolului al XIX-lea, Timiºoara a devenit locul unei descoperiri ºtiinþifice epocale, care a schimbat radical dezvoltarea geometriei, a ºtiinþei spaþiului, a matematicii ºi fizicii.
Pe lângã îndeplinirea obligaþiilor de serviciu, János Bolyai ºi-a continuat la Timiºoara cercetãrile începute în anii studenþiei la Viena, axate pe complexa problemã a paralelelor. În 3 noiembrie 1823, într-o lungã scrisoare adresatã tatãlui sãu, care activa ca profesor la Gimnaziul superior reformat din Târgu Mureº, tânãrul inginer militar anunþa cã a izbutit sã înfãptuiascã lucruri minunate prin descoperirea formulei fundamentale a primei geometrii neeuclidiene. „... Din nimic am creat o altã lume, nouã“, scria el în scrisoare, realizând importanþa ºtiinþificã a descoperirii fãcute.

http://www.math.ubc.ca/~robles/hyperbolic/eucl/prll/Lobachevsky-Bolyai-Gauss.htm
Nicolai Ivanovich Lobachevsky
Lobachevsky published the first account of non-euclidean geometry. He derived his trigonometry formulas from the study horocycles and the horoshpere, rediscovering Watcher's theorem that the geometry of horocycles on the horosphere is the same as lines in the euclidean plane. Lobachevsky established the independence of Euclid's fifth postulate by pointing out that the geometry is entirely based on his formulae for a triangle which leads to the familar formulae for spherical triangles when sides a b c are replaced by ia ib ic . So any inconsistancy in the geometry would imply an inconsistancy in the spherical geometry which is part of euclidean geometry.
Bolyai Janos
...a new universe from nothing. J Bolyai was the founder of Absolute Geometry that branch of geometry consisting of those propositions independent of the fifth postulate (and therefore appiciable to euclidean and hyperbolic geometry). Bolyai and Lobachevsky discovered non-Euclidean geometry simultaneously. Bolyai became interested in the theory of parallel lines under the influence of his father Bolyai Farkas . F Bolyai himself devoted considerable energy toward a proof the parallel postulate without success and tried to dissuade his son from such a hopeless endevor: I entreat you, leave the doctrine of parallel lines alone; you should fear it like a sensual passion; it will deprive you of health, leisure and peace it will destroy all joy in your life.

Ezt követoen Váradi hallgató szavalta el Babits Mihály Bolyai János címuversét, Vígh tözsormester németül idézett bolyai farkas leveleibol.
http://www.zmka.hu/Forum/02ond/zaszlo.htm
Az egykori m. kir. Bolyai János Honvéd Mûszaki Akadémia, jogutódja a Fõiskolai kar és a Honvéd Alapítvány névadója születésének kétszázadik évfordulóját ünnepeltük ebben az évben. A sok nagyszerû rendezvény közül is kiemelkedett a Honvéd Alapítvány szervezésében Bolyai János bécsi emléktáblájának megkoszorúzása.
Az emlékünnepségre utazó delegáció vezetõje Dr. Piószeghy János nyá. dandártábornok, mb. katonai rektorhelyettes volt, díszvendégként megjelent Dr. Farkas Tivadar nyá. mk. vezérõrnagy, aki a Nemzetvédelmi Akadémia parancsnokával hat évvel ezelõtt együtt avatta fel az emléktáblát.
Bécs helyõrségi templomában, a Stift templomban az emléktábla mellé felállt a Bécsi Gárda és a magyar hallgatók díszõrsége. Ünnepélyes orgonazenére hozták be hallgatóink a történelem viharait megélt Bolyai zászlót, és vitték az oltár mellé. A nagyszámú meghívottak orgonakísérettel énekelték el nemzeti himnuszaikat. Rudolf Schütz tábornok, az Osztrák Szövetségi Haderõ Katolikus Tábori Püspökség általános helynöke köszöntötte a megjelenteket. Imájában megemlékezett az egykori Bolyai Akadémia és a mai Fõiskolai Kar elhunyt hallgatóiról. Dr. Szabó Tamás katolikus tábori püspök és Jákob János alezredes protestáns tábori esperes szolgált az oltárnál. Váradi Tibor hallgató magyarul és Vígh Krisztina törzsõrmester hallgató németül idéztek a Szent Leckébõl. Ezt követõen Váradi hallgató szavalta el Babits Mihály: Bolyai János címû versét, Vígh tözsõrmester németül idézett Bolyai Farkas leveleibõl.

Euclidean geometry. Written in Latin, it was meant as a complementarywork to his father's, bolyai farkas, manual titled Tentamen .
http://www.ici.ro/romania/science/bolyai.html
Great Hungarian mathematician from Transylvannia. He studied at the Academy for Engineers Corps in Vienna. He made a brilliant figure while being a student by his significant findings. His crucial work, called "Appendix", which he had written in 1832, in no realisation of what Russian mathematician N. I. Lobacevski was doing almost at the same time, fathered the non-Euclidean geometry. Written in Latin, it was meant as a complementary work to his father's, Bolyai Farkas, manual titled: "Tentamen". In 1837 Bolyai also dedicated his study "Responsio" to complex numbers theory. His findings are dialectical contributions to mathematical problems, as he laid new foundations to geometry and prepared it for new horizons. Regrettably, his work received no due attention and appreciation from his contemporaries. Last update : 2000, January 21 Go to

Bolyai, Janos (1802-1860)

Hungarian mathematician who was the son of Farkas Bolyai . When Bolyai began puzzling over Euclid's fifth postulate his father wrote him "For God's Sake, I beseech you, give it up. Fear it no less than sensual passions because it, too, may take all your time, deprive you of your health, peace of mind, and happiness in life" (Boyer 1968, p. 587). Janos did not heed his father, however, and his work, which paralleled that of Lobachevsky , was published by his father. However, Bolyai's lack of recognition and the publishing of Lobachevsky's work led him to publish nothing more. Bolyai (Farkas) Lobachevsky

Farkas Wolfgang Bolyai
(Bolya 1775 - Marosvasarhely 1856) Mathématicien hongrois. Il enseigna les mathématiques, la physique et la chimie à Marosvasarhely toute sa vie. Contemporain de Gauss, il entretient avec lui une longue correspondance. Il s'intéresse aux fondements de la géométrie et plus particulièrement au cinquième postulat d'Euclide. Janos Bolyai
(Kolozsvar 1802 - Marosvasarhely 1860) Son fils Janos (1802-1860), officier du génie, consacre ses loisirs à la construction d'une nouvelle géométrie en remplaçant le cinquième postulat d'Euclide par l'axiome suivant : 'Par tout point extérieur à une droite il passe une infinité de parallèles à cette droite'. Gauss approuve totalement ses recherches et signale qu'il connait déjà ces résultats depuis de nombreuses années : Lobatchevski était arrivé au même résultat que lui. Déçu de ne pas être le premier mathématicien à avoir trouvé cette nouvelle géométrie (géométrie non-euclidienne), Bolyai ne publie plus aucun résultat.
A noter cependant que l'on appelle quelque fois la géométrie dite de Lobatchevski, la géométrie de Bolyai.

Aceitou, então um lugar no novo Departamento de Matemática.Física e Quimica, no colégio; mas a baixo salário , forçava-o a procurar outras fontes de rendimentos. Quase completamente isolado no seu retiro em Marosvásárhely mesmo assim, tentou desenvolver o seu sistema de matemática; em 1832/33, publicou "TENTAMEN", o resultado de muita meditação de um cientíta que não podia apoiar-se se não num par de livros; contém uma grande quantidade de material em vários campos da matemática, com diversos conhecimentos matemáticos acumulados desde o começo até ao último século.
